(Sunman, Ind.) - Residents in the Sunman Fire Department service area may observe some fluctuation in water pressure Wednesday morning.

The fire department, Sunman Water Utility, Hoosier Hills Water Company and North Dearborn Water Company are working on an ISO survey for the Sunman Fire protection area. The survey will assist insurance companies in establishing a Fire Protection Rate for homeowners and properties in our area.

This testing will start at 8:00 a.m. and should finish by noon with residents and businesses noticing sometimes low water pressure.
